If the regulator isn’t receiving sufficient voltage, of course it will not be able to output its rated regulated voltage.

We volhage the voltage input into the voltage regulator and the voltage output from the regulator. This is normally volts higher. To test the voltage going into the voltage regulator, we take a multimeter and place it in the DC voltage setting.

Measuring the Input Voltage When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground. If the multimeter does read a voltage near its rated output voltage, the voltage regulator is functional and is good. As an example, we’ll use the popular voltage regulator, the LM The voltage that we should read should be higher than the voltage the regulator is rated to output.

If we read at the input pin the voltage which we feed into the vkltage and read at the output pin the output voltage which the regulator is rated for, then we know that the voltage regulator is good. How To Test a Voltage Regulator A voltage regulator is a device that takes in an input voltage and regulates it down to the voltage that it is rated for.

How To Test a Voltage Regulator

To measure the output voltage, we place the same multimeter set in the DC voltage setting and now place the positive probe of the multimeter on the output pin of the regulator and the negative probe on the ground pin of the regulator. If we do not, then the voltage regulator is defective, as it does not do the job it was eh111a for, which is output a regulated voltage. So we’ll now go through specifically how to test a voltage regulator.

Being that a voltage regulator passes out a regulated output voltage, the only test we must do to check a voltage regulator is a voltage test. Measuring regulatr Output Voltage Now that this step is complete, we now read the output voltage.

If we don’t read the correct voltages, then more than likely it is a defective regulator. The ground pin is pin 2. This is to make sure that voltage is, in fact, being supplied to the regulator.

Before we get into how to read the voltages with a multimeter, first we’ll go over the pinout of a voltage regulator, so that you’ll know which pins to read voltages from.

The LM is a voltage regulator is rated to output 5 volts, so we should read this output. Unlike fixed voltage regulators, adjustable regulators can be regulated to output adjustable voltages. The DC voltage setting is the setting volfage the multimeter that has the following symbol or sign. If the regulator is rated to output 5 voltgae, then we should read a voltage very near 5 volts coming out from its output.

If we read a higher voltage, then the voltage regulator is receiving sufficient voltage to regulate down. This is why we do this test. All a user must do is calculate the output that the regulator should output and perform the same test as is shown above to see whether it is good or defective. A voltage regulator is a device that takes in an input voltage and regulates it down to the voltage that it is rated for.

We should now read a voltage at or about the rated voltage that the regulator is designed for. Below is the pinout of voltae LM voltage regulator: And the regulated output voltage comes out from pin 3 Output.

An adjustable regulator can be tested in the same way. The input voltage that needs to be regulated down goes into pin 1 Input. We take the probes of the multimeter and place regulatlr positive probe normally the red probe on the input pin of the voltage regulator and the negative probe normally black probe on the ground pin.
